Abstract

The study conducted in the silvipastoral system indicated that the collar diameter, DBH and tree height for stands of Dalbergia sissoo, Gmelina arborea, Pongamia pinnata and Terminalia arjuna were ranged from 12.01 to 15.03 cm, 9.06 to 13.1 cm and 5.40 to 7.19 m respectively. The over all dry matter production was found in order of a D.sissoo (45.18 kg tree^-1) G. arborea (36.97 kg tree-1) P. pinnata (26.74 kg tree-1) and T. arjuna (23.12 kg tree -1). The under storey pasture crop of Chrysopogon fulvus > Stylosanthes hamata get established during initial growing stage of silvipasture system. As soon as the tree canopy developed the invasion of local/ native flora gets interacted with the growing species and started to influence the quality and quantity production of established pasture crops which ultimately increase the productivity of forage grasses. The study indicated that Dalbergia sissoo and Gmelina arborea species based silvipasture system was found comparatively more suitable for development and utilization of red lateritic wasteland. The systematic compatible tree-grass-legumes combination was observed better for optimum growth and biomass production as well as conservation of environment.

Abstract

Prosopis cinerea (Leguminasae) is a hardy tree species and mostly grown in arid and semi arid zones. In Chhattisgarh semiarid conditions appear in Entisols just after the rainy seasons. A nursery trial was conducted using Entisols supplemented by FYM in different ratio viz; 0 (T₁), 25 (T₂), 33 (T₃), 50 (T₄), 67 (T₅), 75 (T₆) and 100 per cent (T₇). The emergence of seedling was 64.3 per cent in T₁, T₅ and T₆ while 57.1 per cent in T₂, T₃ and T₄ with minimum in T₇ (42.9%). Survivorship of seedling was ranged 81.3 to 88.9 per cent. The growth in shoot, ischolar_main length and dry matter accumulation was highest in T₇ (Pure FYM) followed by T₆ (75% FYM) with decreasing trend as share of FYM get decreased till T₁ (Pure soil). The observations were found statistically insignificant between T₁ to T₅ and T₅ to T₇ . The positive correlation among soil and plant parameters showed that availability of nitrogen in soil played very significant role for growth of stem, leaves and ischolar_mains, while availability of phosphorus promote growth in stem and ischolar_mains only. There was strong negative relationship between organic carbon and emergence of seedlings, resulted the least emergence in T₇ (42.9 %) due to toxicity causes by organic matters. Thus over all the application of FYM particularly in the ratio of 1:2 and 1:3 with Entisols in treatment T₅ and T₆ respectively were found better for raising the seedling and plants of Prosopis cinerea.
